I PERSONALLY DONT GO TO California casinos ( i dont feel the odds are as good as Vegas )
But , directly north of you'r temporary location , up the 5 frwy north , there is the commerce casino , (in commerce) , and the Hustler casino (larry flynt ) both not more than 30 min. north

if there are others , either i dont know about them , or they are far , far away

If you want to know where one is , if you know the name , or place , i will be glad to help you in relation to the airport as to where it is......I live here in O >C> , but spend most of MY time in Vegas , Or out on the ocean
